Which of the following best describes a diurnal animal?

A diurnal animal is characterized by being primarily active during the daytime. This means that these animals have adapted their behaviors and biological rhythms to coincide with the daylight hours, engaging in activities such as foraging, mating, and social interactions when it is light outside.

This activity pattern might provide several advantages such as better visibility, which aids in foraging for food and avoiding predation. Many birds, some mammals, and a variety of reptiles are examples of diurnal animals, taking advantage of the warmth and light available during the day.

In contrast, the other options describe different patterns of activity. For instance, nocturnal animals are active during nightfall, while crepuscular animals are primarily active at twilight, and some species may exhibit a more generalized pattern of activity throughout both day and night. However, since the focus is on diurnal animals specifically, the definition aligns with being primarily active in the daytime.
